Further, the plants essential oil with penetrating odor is contained with the air accumulator.
Further, pressure sensor, the pressure sensor and control cabinet electricity are provided with each seal cavity
Property connection, the control cabinet electrically controls the switch of the air-introduced machine connected with air accumulator to open and close.
Further, the waterproof layer is polyester non-woven fabric waterstop.
Further, multiple reinforced supports are in axial direction also evenly arranged with the seal cavity of the protecting pipe, often
Multiple through holes are offered on individual reinforced support.
Further, the protecting pipe is made up of PVC material.
Further, the distance between two adjacent connecting tubes are in the range of 30-50m.
Further, extend and be provided with switch valve in the connecting tube of the steel wire armor layer.
Compared with prior art, the beneficial effects of the utility model are as follows：
1. the gas with penetrating odor can be passed through by the utility model by setting the protecting pipe with hollow cavity
In the cavity, effect is prevented well so as to be played to mouse sting；
2. compared with expelling parasite material is fixed in the placement of prior art, gas can be more easy to control, can regularly replace different gas
The gas of taste, prevent that mouse worm is immune to same smell or adapts to；
3. outermost layer of the present utility model is steel wire armor layer, further protection is played to mouse sting, improves cable
Service life.

Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the utility model is clearly and completely described, it is clear that retouched
The embodiment stated is only preferred embodiment of the present utility model, rather than whole embodiments.Based in the utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of the utility model protection.
Embodiment
Refer to the attached drawing, Fig. 1 are the cross-sectional structure schematic diagram of the photovoltaic cable of protection against rodents sting of the present utility model；And
Fig. 2 is the partial longitudinal section structural representation of the photovoltaic cable of protection against rodents sting of the present utility model.
Specifically, the photovoltaic cable of protection against rodents sting of the present utility model, it includes conductor 1, isolation successively from inside to outside
Layer 2, insulating barrier 3, screen layer 4, waterproof layer 5, the protecting pipe 6 with hollow cavity being set in outside the waterproof layer 5 and
The steel wire armor layer 7 being coated on outside protecting pipe 6.Wherein, insulating barrier of the present utility model uses irradiation cross-linking flame-retardant polyolefin
Material, there is excellent physical mechanical performance, high-low temperature resistant and high flame resistance, solve insulating properties and high flame retardant can
The problem taken into account；Protecting pipe 6 is made up of PVC material, and preferable protective action is played to cable, have waterproof, stability good etc.
Advantage；Waterproof layer is polyester non-woven fabric waterstop, can play double-deck water-proof wire jointly with protecting pipe, avoids the moisture or wet of outside
Gas enters inside cable.
The hollow cavity of protecting pipe 6 is provided with back-up ring 8 with by protecting pipe 6 in the axial direction spaced apartly
Hollow cavity is divided into multiple seal cavities 9, and each seal cavity is connected by connecting tube 10 with the air accumulator of outside；Storage
The gas with irritative gas is stored in gas tank.In use, the irritative gas that air accumulator pipe stores is passed through to shield
In the seal cavity of sleeve pipe, because the smell of mouse worm is sensitiveer, the irritative gas in seal cavity, which can play, drives mouse worm
Effect.
In order to which the effect of protection against rodents sting is better achieved, the plant essence with penetrating odor can be contained with air accumulator
Oil, it is well known that plants essential oil has very big smell in use and mouse worm dislikes the smell, thus the gas in air accumulator can
Be mixed into the plants essential oil of volatilization and with plants essential oil smell gas be filled with photovoltaic cable protecting pipe seal cavity
In.However, the penetrating odor is not intended to limit and this, or champignon etc. is to the effective gas of expelling parasite.
Pressure sensor is provided with each seal cavity 9, pressure sensor and a control cabinet are electrically connected with, control cabinet
The switch of the air-introduced machine connected with air accumulator is electrically controlled to open and close.By the setting of pressure sensor, it can perceive and be filled with annular seal space
Internal air pressure, when the air being filled with reaches certain pressure, then pressure sensor can transmit signals to control cabinet, from
And the keying for controlling the air-introduced machine of air accumulator to switch.
When being passed through same gas for a long time, mouse worm is then immune to the smell or has adapted to the smell, then starts pair
Mouse worm is bitten, by structure of the present utility model then can by the seal cavity of protecting pipe air extract out be filled with it is new not
Same smell, so as to further prevent biting for mouse worm.
In a preferred embodiment, as shown in Figure 1, it is in axial direction also uniform in the seal cavity 9 of protecting pipe 6
Multiple reinforced supports 11 are provided with, multiple through holes are offered on each reinforced support 11.It can be increased by reinforced support and through hole
Add the bending pliability that cable is also kept while protecting pipe intensity, and cause be between the seal cavity between two back-up rings
The structure of connection.
In addition, in order that the utility model there is more preferable practicality, extend in the connecting tube 10 of steel wire armor layer
It is provided with switch valve.The switch valve can be removably threadedly coupled with air accumulator, thus operating personnel can be photovoltaic by stages
Cable is handled.The distance between two adjacent connecting tubes 10 are 30-50 rice, and it is simultaneously nonrestrictive, and it can be any
Suitable distance.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
